Description

Technical Field

[0001] The present invention relates to the technical field of transportation devices, and more specifically, to an automatic feeding and empty-return device. Background Art

[0002] Parts are usually placed in boxes. After the boxes are filled with parts at the first station, the full boxes need to be fed to the second station for further processing of the parts, and then the empty boxes are returned to the first station for reuse. Setting up a separate device for feeding and empty-return respectively will occupy a large amount of space, and a set of driving mechanisms need to be set up separately to drive automatic feeding and automatic empty-return.

[0003] The prior art discloses an automatic feeding and empty-return device, including a material storage and empty-return part and a picking and empty-return lifting device. Among them, the material storage and empty-return part includes at least one upper feeding layer for carrying full box packaging boxes and one lower feeding layer for carrying empty box packaging boxes. The picking and empty-return lifting device is arranged at the picking point, and the picking and empty-return lifting device drives the packaging box to switch positions between the corresponding upper feeding layer and the lower feeding layer. The picking and carrying part is provided with a second box pushing device for transferring the empty box packaging box. Integrating the upper feeding layer (feeding) and the lower feeding layer (empty-return) into one device not only realizes single-point automatic feeding but also realizes single-point automatic empty-return. The equipment occupies a small space and is convenient for layout. However, this device still needs to use the second box pushing device to move the packaging box located on the picking and empty-return lifting device to the lower feeding layer, and multiple drives are used for overall control of the device. Summary of the Invention

[0004] An object of the present invention is to overcome the deficiency of overall using multiple drives for control in the prior art, and provide an automatic feeding and empty-return device that is controlled by only one drive.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: Provide an automatic feeding and empty-return device, including a mounting frame, a feeding component, an empty-return component and a lifting device. The feeding component and the empty-return component are both arranged on the mounting frame, and both ends of the lifting device are respectively connected with the feeding component and the empty-return component; the lifting device includes a lifting mechanism, a lifting frame and a turning platform. Both ends of the lifting mechanism are respectively connected with the feeding component and the empty-return component. The lifting frame is connected with the output end of the lifting mechanism, the turning platform is rotatably connected with the lifting frame, and a blocking rod for blocking the turning platform is arranged on the mounting frame. The blocking rod is located at the feeding port of the empty-return component, and the blocking rod is parallel to the rotation axis of the turning platform.

[0006] The automatic feeding and emptying device of the present invention, when in use, places the full boxes of products on the feeding component. The feeding component transports the full boxes of products to the turning platform of the lifting device. The lifting frame supports the turning platform. The turning platform is located at the required working station. After the staff takes out the products, the lifting mechanism is started to transport the empty boxes to the emptying component. When the lifting mechanism drives the turning platform to move to the blocking rod, the blocking rod blocks the further movement of the turning platform. At this time, if the lifting mechanism drives the turning platform to move further, the turning platform will rotate, so that the turning platform tilts towards the feeding port of the emptying component. At this time, the empty boxes on the turning platform slide towards the emptying component under the action of gravity, and the emptying component returns the empty boxes to the previous working station. By setting the turning platform and the blocking rod, after the lifting mechanism drives the turning platform to move to the feeding port of the emptying component, the blocking rod blocks the turning platform, so that the turning platform rotates, and the empty boxes on the turning platform automatically enter the emptying component. There is no need to use other control devices to move the empty boxes to the emptying component, and only one drive is used for control, so the control is simple; and when the turning platform is aligned with the feeding port of the emptying component, the empty boxes immediately move towards the emptying component, and the production beat is short.

[0007] Further, the lifting mechanism includes a cylinder, a first transmission component and a linear guide rail. The cylinder and the linear guide rail are both arranged on the mounting frame. Two ends of the first transmission component are respectively connected with the output end of the cylinder and the lifting frame. The lifting frame is slidably connected with the linear guide rail. When the cylinder is started, the cylinder drives the lifting frame to move along the linear guide rail through the first transmission component.

[0008] Further, the first transmission component includes a first fixed pulley a, a second fixed pulley b and a first transmission rope c. The first fixed pulley a is rotatably arranged on the lifting frame. The second fixed pulley b is rotatably arranged on the top of the mounting frame or the top of the linear guide rail. The second fixed pulley b is located at the top of the linear guide rail. The first transmission rope c is wound around the first fixed pulley a and the second fixed pulley b. The first transmission rope c is connected with the output end of the cylinder. When the output end of the cylinder moves, the distance between the output end of the cylinder and the second fixed pulley b changes. The cylinder pulls the first transmission rope c, changes the distance between the first fixed pulley a and the second fixed pulley b, and drives the lifting frame to move.

[0009] Further, it further includes a first blocking component. The first blocking component is connected with the mounting frame. The first blocking component is located at the discharge port of the feeding component. By setting the first blocking component, the full boxes at the discharge port of the feeding component are blocked, and the full boxes are released after the turning platform is aligned with the discharge port of the feeding component.

[0010] Furthermore, the first blocking component includes a blocking frame and a second transmission component. The blocking frame is slidably connected to the mounting frame. The blocking frame is located at the discharge port of the feeding component. The second transmission component is connected to the blocking frame and is located at the discharge port of the feeding component. A first trigger rod for triggering the second transmission component is provided on the lifting frame. When the first trigger rod does not contact the second transmission component, that is, when the lifting frame is not at the bottom of the linear guide rail, the blocking frame blocks the discharge port of the feeding component to prevent the full box from moving and avoid the full box from falling off the device. When the first trigger rod contacts the second transmission component, the second transmission component drives the blocking frame to move, leaving enough space for the full box to move to the tipping table. No additional control equipment is required for control, and the control is simple. Moreover, after the lifting frame is located at the discharge port of the feeding component, the full box can immediately move to the tipping table, and the production cycle is short.

[0011] Furthermore, the emptying component is located above the feeding component. The blocking frame is in a U-shaped configuration. The second transmission component includes a lever. The lever is rotatably connected to the mounting frame. One end of the lever abuts against the bottom of the blocking frame, and the other end of the lever is directly below the first trigger rod. When the lifting frame moves to the bottom of the linear guide rail, the lifting frame presses down the other end of the lever, and one end of the lever rises, driving the U-shaped blocking frame to rise, leaving enough space for the full box to move.

[0012] Furthermore, a second blocking component is further included. The second blocking component is connected to the mounting frame. The first blocking component is located between the second blocking component and the tipping table. The distance from the second blocking component to the first blocking component is equal to the width of the box body. By providing the second blocking component, the subsequent full boxes are blocked, and only one box body enters the tipping table when the blocking of the first blocking component is released.

[0013] Furthermore, the second blocking component includes a blocking plate, an elastic member, and a third transmission component. The blocking plate is slidably connected to the mounting frame. The two ends of the elastic member are respectively connected to the blocking plate and the mounting frame. The blocking frame is located between the blocking plate and the tipping table. The distance from the blocking frame to the blocking plate is equal to the width of the box body. The third transmission component is connected to the blocking plate. A second trigger rod for triggering the third transmission component is provided on the output end of the air cylinder. When the air cylinder starts to drive the lifting frame to rise, the air cylinder drives the blocking plate to descend through the third transmission component, and the elastic member is compressed, enabling the full box abutting against the blocking plate to move to the first blocking component. When the air cylinder returns to its original position, the blocking plate is reset under the drive of the elastic member to block the subsequent full boxes, ensuring that there is only one full box between the blocking plate and the first blocking component. After the first blocking component moves, only one full box enters the tipping table.

[0014] Furthermore, the third transmission assembly includes a rotating rod, a rotating sleeve, a toggle rod, a connecting rod and a second transmission rope, the rotating rod is arranged on the mounting frame, the rotating sleeve is rotatably connected to the rotating rod, the toggle rod and the connecting rod are both arranged on the rotating sleeve, an angle is formed between the toggle rod and the connecting rod, the toggle rod is located between the second trigger rod and the cylinder body, the two ends of the second transmission rope are respectively connected to the connecting rod and the blocking plate, and the connecting rod is located below the blocking plate. When the cylinder is started, the cylinder drives the second trigger rod to move toward the toggle rod, and after the second trigger rod abuts against the toggle rod, the toggle rod drives the rotating sleeve to rotate on the rotating rod, drives the connecting rod to rotate, and the distance between the connecting rod and the blocking plate becomes larger, and the blocking plate is driven to move downward toward the connecting rod through the second transmission rope, thereby driving the blocking plate to descend.

[0015] Furthermore, the return assembly is provided with a pneumatic mechanical valve, and an air pipe is connected between the pneumatic mechanical valve and the cylinder. When the empty box moves to the return assembly, the pneumatic mechanical valve is triggered, and the cylinder moves in the reverse direction to reset, so as to facilitate the next cycle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. An automatic loading and emptying device of the present invention is provided with a turning table and a blocking rod. When the lifting mechanism drives the turning table to move to the feed port of the emptying component, the blocking rod blocks the turning table, so that the turning table can rotate, and the empty box on the turning table automatically enters the emptying component. There is no need to use other control devices to move the empty box to the emptying component. Only one drive is used for control, and the control is simple. When the turning table is aligned with the feed port of the emptying component, the empty box immediately moves toward the emptying component, and the production cycle is short.

[0017] 2. An automatic loading and returning device of the present invention, when the first trigger rod does not contact the second transmission assembly, that is, when the lifting frame is not located at the bottom of the linear guide rail, the blocking frame blocks the discharge port of the loading assembly to block the movement of the full box and prevent the full box from falling from the device; when the first trigger rod contacts the second transmission assembly, the second transmission assembly drives the blocking frame to move, leaving enough space for the full box to move to the turning table, without the need for additional control equipment, and the control is simple; and after the lifting frame is located at the discharge port of the loading assembly, the full box can be immediately moved to the turning table, and the production cycle is shorter.

[0018] 3. An automatic loading and returning device of the present invention, when the cylinder is started to drive the lifting frame to rise, the cylinder drives the blocking plate to descend through the third transmission assembly, and the elastic member is compressed, so that the full box abutting against the blocking plate can move to the first blocking assembly. When the cylinder returns to its position, the blocking plate is reset under the drive of the elastic member to block the subsequent full boxes, so that there is only one full box between the blocking plate and the first blocking assembly. After the first blocking assembly moves, only one full box enters the turning table. No additional control equipment is required, and the control is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment 1 This embodiment is the first embodiment of an automatic feeding and emptying device. As Figure 1 shown, it includes a mounting frame 100, a feeding assembly 200, an emptying assembly 300, and a lifting device 400. The feeding assembly 200 and the emptying assembly 300 are both arranged on the mounting frame 100. In this embodiment, the feeding assembly 200 gradually slopes downward towards the lifting frame 420, and the emptying assembly 300 gradually slopes upward towards the lifting frame 420. Flow bars can be installed on the upper surfaces of the feeding assembly 200 and the emptying assembly 300 to reduce the friction between the box and the feeding assembly 200 and the emptying assembly 300, facilitating the movement of the box under the action of gravity.

[0024] Both ends of the lifting device 400 are respectively connected to the feeding assembly 200 and the emptying assembly 300. As Figure 2 and Figure 3 shown, the lifting device 400 includes a lifting mechanism 410, a lifting frame 420, and a turning platform 430. Both ends of the lifting mechanism 410 are respectively connected to the feeding assembly 200 and the emptying assembly 300. The lifting frame 420 is connected to the output end of the lifting mechanism 410. The turning platform 430 is rotatably connected to the lifting frame 420. A blocking rod 110 for blocking the turning platform 430 is provided on the mounting frame 100. The blocking rod 110 is located at the feeding port of the emptying assembly 300, and the blocking rod 110 is parallel to the rotation axis of the turning platform 430. In the normal state, the turning platform 430 is supported by the lifting frame 420 and is horizontally arranged. When the turning platform 430 abuts against the blocking rod 110, the lifting frame 420 continues to move, and the turning platform 430 rotates to make the turning platform 430 slope downward towards the feeding end of the emptying assembly 300.

[0025] As Figure 2 and Figure 4As shown in the figure, the turning table 430 includes a mounting plate 431, an inclined plate 432 and a baffle 433. The mounting plate 431 is rotatably connected to the lifting frame 420. The inclined plate 432 is arranged on the mounting plate 431. The top surface of the inclined plate 432 gradually slopes upward toward the feeding assembly 200. A skate can be installed on the upper surface of the inclined plate 432 to reduce the friction between the box and the inclined plate 432, which is beneficial to the movement of the box under the action of gravity. The baffle 433 is arranged at one end of the mounting plate 431 away from the feeding assembly 200. When the full box moves from the feeding assembly 200 to the inclined plate 432, the full box abuts against the baffle 433 under the action of gravity, so that the full box completely moves onto the turning table 430, avoiding the full box from falling during lifting. At this time, the overall center of gravity of the turning table 430 is biased toward the end away from the empty-returning assembly 300, causing the turning table 430 to tilt toward the end away from the empty-returning assembly 300, thereby preventing the full box from moving toward the empty-returning assembly 300. The lifting frame 420 supports the turning table 430 at the bottom to prevent the turning table 430 from rotating excessively. After the lifting mechanism 410 drives the lifting frame 420 to move to the feeding port of the empty-returning assembly 300, the blocking rod 110 abuts against the mounting plate 431. As the lifting frame 420 further moves, the inclined plate 432 rotates toward the empty-returning assembly 300, causing the upper surface of the inclined plate 432 to tilt downward as a whole toward the empty-returning assembly 300, allowing the empty box to slide onto the empty-returning assembly 300 under the action of gravity.

[0026] The working principle of the automatic feeding and empty-returning device in this embodiment is as follows: During use, place the full-box products on the feeding assembly 200. The feeding assembly 200 transports the full-box products to the turning table 430 of the lifting device. The lifting frame 420 supports the turning table 430. The turning table 430 is located at the required working station. After the staff removes the products, start the lifting mechanism 410 to transport the empty box to the empty-returning assembly 300. When the lifting mechanism 410 drives the turning table 430 to move to the blocking rod 110, the blocking rod 110 blocks the further movement of the turning table 430. At this time, if the lifting mechanism 410 drives the turning table 430 to move further, it will cause the turning table 430 to rotate, so that the turning table 430 tilts toward the feeding port of the empty-returning assembly 300. At this time, the empty box located on the turning table 430 slides toward the empty-returning assembly 300 under the action of gravity, and the empty-returning assembly 300 returns the empty box to the previous working station. By setting the turning table 430 and the blocking rod 110, after the lifting mechanism 410 drives the turning table 430 to move to the feeding port of the empty-returning assembly 300, the blocking rod 110 blocks the turning table 430, causing the turning table 430 to rotate. The empty box located on the turning table 430 automatically enters the empty-returning assembly 300 without using other control devices to move the empty box to the empty-returning assembly 300. Only one drive is used for control, and the control is simple; and when the turning table 430 is aligned with the feeding port of the empty-returning assembly 300, the empty box immediately moves toward the empty-returning assembly 300, and the production cycle is short.

[0027] Embodiment 2 This embodiment is the second embodiment of the automatic feeding and emptying device. This embodiment is similar to Embodiment 1, except that, as Figure 2 shown, the lifting mechanism 410 includes a cylinder 411, a first transmission assembly 412, and a linear guide 413. Both the cylinder 411 and the linear guide 413 are arranged on the mounting frame 100. The two ends of the first transmission assembly 412 are respectively connected to the output end of the cylinder 411 and the lifting frame 420. The linear guide 413 can be arranged vertically or obliquely, as long as the two ends are respectively aligned with the feeding assembly 200 and the emptying assembly 300. In this embodiment, the linear guide 413 is arranged vertically, and the lifting frame 420 is slidably connected to the linear guide 413. When the cylinder 411 is started, the cylinder 411 drives the lifting frame 420 to move along the linear guide 413 through the first transmission assembly 412.

[0028] In this embodiment, the cylinder can be an electric cylinder or a pneumatic cylinder. When using an electric cylinder, a control button can be arranged on the device. The control button is electrically connected to the cylinder 411. The control button is located at the turning table 430, which is convenient for the staff to directly press the control button to control the movement of the cylinder 411 after the parts in the full box are processed; when using a pneumatic cylinder, a main valve can be arranged on the device. The main valve is communicated with the cylinder 411 through an air pipe. The main valve is located at the turning table 430, which is convenient for the staff to directly press the control button to control the movement of the cylinder 411 after the parts in the full box are processed.

[0029] A pneumatic mechanical valve is arranged on the emptying assembly 300, and an air pipe is communicated between the pneumatic mechanical valve and the cylinder. When the empty box moves to the emptying assembly 300, the pneumatic mechanical valve is triggered, and the cylinder moves in the reverse direction to reset, which is convenient for the next cycle. The pneumatic mechanical valve in this embodiment is set as a roller pneumatic mechanical valve.

[0030] As Figure 3 shown, the first transmission assembly 412 includes a first fixed pulley 412a, a second fixed pulley 412b, and a first transmission rope 412c. The first fixed pulley 412a is rotatably arranged on the lifting frame 420. The second fixed pulley 412b is rotatably arranged at the top of the mounting frame 100 or the top of the linear guide 413. The second fixed pulley 412b is located at the top of the linear guide 413. The first transmission rope 412c is wound around the first fixed pulley 412a and the second fixed pulley 412b, and the first transmission rope 412c is connected to the output end of the cylinder 411. When the output end of the cylinder 411 moves, the distance between the output end of the cylinder 411 and the second fixed pulley 412b changes. The cylinder 411 pulls the first transmission rope 412c, changes the distance between the first fixed pulley 412a and the second fixed pulley 412b, and drives the lifting frame 420 to move. The output end of the cylinder 411 can face the linear guide 413 or be back to the linear guide 413. In this embodiment, as Figure 2As shown in the figure, the air cylinder 411 is located at the bottom of the mounting bracket 100, and the output end of the air cylinder 411 faces the linear guide rail 413. A third fixed pulley and a fourth fixed pulley are provided on the mounting bracket 100 for steering. The third fixed pulley steers the first transmission rope 412c along the telescopic direction of the air cylinder 411 to the bottom end of the first fixed pulley 412a, and the fourth fixed pulley steers the first transmission rope 412c from the horizontal direction to the vertical direction. To prevent the first transmission rope 412c from falling off, a connecting ring for connecting the first transmission rope 412c is provided at the top of the mounting bracket 100. That is, the first transmission rope 412c is successively located on the output end of the air cylinder 411, the third fixed pulley, the fourth fixed pulley, the second fixed pulley 412b, the connecting ring, and the first fixed pulley 412a. When the air cylinder 411 contracts, the distance between the output end of the air cylinder 411 and the third fixed pulley becomes larger. The output end of the air cylinder 411 pulls the first transmission rope 412c, and the first transmission rope 412c drives the first fixed pulley 412a to move towards the second fixed pulley 412b. When the air cylinder 411 extends, the lifting frame 420 resets under the action of gravity.

[0031] Embodiment III This embodiment is the third embodiment of the automatic feeding and emptying device. This embodiment is similar to Embodiment I, except that, as Figure 1 shown, it further includes a first blocking component 500. The first blocking component 500 is connected to the mounting bracket 100 and is located at the discharge port of the feeding component 200. By setting the first blocking component 500, the full box located at the discharge port of the feeding component 200 is blocked, and the full box is released after the turning table 430 is aligned with the discharge port of the feeding component 200.

[0032] As Figure 2 shown, the first blocking component 500 includes a blocking frame 510 and a second transmission component 520. The blocking frame 510 is slidably connected to the mounting bracket 100 and is located at the discharge port of the feeding component 200. The second transmission component 520 is connected to the blocking frame 510 and is located at the discharge port of the feeding component 200. A first trigger rod for triggering the second transmission component 520 is provided on the lifting frame 420. When the first trigger rod does not contact the second transmission component 520, that is, when the lifting frame 420 is not located at the bottom of the linear guide rail 413, the blocking frame 510 blocks the discharge port of the feeding component 200 to prevent the full box from moving and avoid the full box from falling off the device; when the first trigger rod contacts the second transmission component 520, the second transmission component 520 drives the blocking frame 510 to move, leaving enough space for the full box to move onto the turning table 430. There is no need for additional control equipment, and the control is simple; and after the lifting frame 420 is located at the discharge port of the feeding component 200, the full box can immediately move onto the turning table 430, and the production rhythm is short.

[0033] As Figure 5As shown, the return assembly 300 is located above the loading assembly 200, the blocking frame 510 is set to be in the shape of a 冂, and the second transmission assembly 520 includes a lever, which is rotatably connected to the mounting frame 100, one end of the lever abuts against the bottom of the blocking frame 510, and the other end of the lever is located directly below the first trigger rod. When the lifting frame 420 moves to the bottom of the linear guide 413, the lifting frame 420 presses down the other end of the lever, and one end of the lever rises, driving the 冂-shaped blocking frame 510 to rise, leaving enough space for the full box to move. When the lifting frame 420 moves to the bottom of the linear guide 413, the lifting frame 420 presses down the other end of the lever, and one end of the lever rises, driving the blocking frame 510 to rise, leaving enough space for the full box to move, so that the full box can move to the turning table 430, without the need for additional control equipment, and the control is simple; and after the lifting frame 420 is located at the bottom, the full box can be immediately moved to the turning table 430, and the production cycle is short. When the first trigger rod does not contact the lever, the U-shaped blocking frame 510 descends under the action of gravity to block the discharge port of the loading assembly 200. The first blocking assembly 500 may also include a tension spring, the two ends of which are respectively connected to the mounting frame 100 and the U-shaped blocking frame 510, and the U-shaped blocking frame 510 steadily descends under the action of gravity and the tension spring to block the discharge port of the loading assembly 200.

[0034] Embodiment 4 This embodiment is the fourth embodiment of the automatic loading and emptying device. This embodiment is similar to the first embodiment, except that Figure 1 As shown, the second blocking assembly 600 is also included, and the second blocking assembly 600 is connected to the mounting frame 100. The first blocking assembly 500 is located between the second blocking assembly 600 and the turning table 430. The distance from the second blocking assembly 600 to the first blocking assembly 500 is not greater than the width of the box. In this embodiment, the distance from the second blocking assembly 600 to the first blocking assembly 500 is equal to the width of the box. By setting the second blocking assembly 600, subsequent full boxes are blocked, and when the blocking of the first blocking assembly 500 is released, only one box enters the turning table 430.

[0035] like Figure 2 and Figure 6As shown, the second blocking assembly 600 includes a blocking plate 610, an elastic member 620 and a third transmission assembly 630. The blocking plate 610 is slidably connected to the mounting frame 100. The two ends of the elastic member 620 are respectively connected to the blocking plate 610 and the mounting frame 100. The blocking frame 510 is located between the blocking plate 610 and the flip table 430. The distance from the blocking frame 510 to the blocking plate 610 is not greater than the width of the box. In this embodiment, the distance from the blocking frame 510 to the blocking plate 610 is equal to the width of the box. The third transmission assembly 630 is connected to the blocking plate 610. A second trigger rod for triggering the third transmission assembly 630 is provided on the output end of the cylinder 411. When the cylinder 411 starts to drive the lifting frame 420 to rise, the cylinder 411 drives the blocking plate 610 to descend through the third transmission assembly 630, and the elastic member 620 is compressed, so that the full box abutting against the blocking plate 610 can move to the first blocking assembly 500. When the cylinder 411 returns to its original position, the blocking plate 610 is reset under the drive of the elastic member 620 to block subsequent full boxes. In the plate embodiment, the elastic member 620 uses a spring to ensure that there is only one full box between the blocking plate 610 and the first blocking assembly 500, so that after the first blocking assembly 500 moves, only one full box enters the turning table 430.

[0036] like Figure 6 As shown, the third transmission assembly 630 includes a rotating rod 631, a rotating sleeve 632, a toggle rod 633, a connecting rod 634 and a second transmission rope 635. The rotating rod 631 is arranged on the mounting frame 100, the rotating sleeve 632 is rotatably connected to the rotating rod 631, the toggle rod 633 and the connecting rod 634 are both arranged on the rotating sleeve 632, and there is an angle between the toggle rod 633 and the connecting rod 634. The toggle rod 633 is located between the second trigger rod and the cylinder body of the cylinder 411. The two ends of the second transmission rope 635 are respectively connected to the connecting rod 634 and the blocking plate 610, and the connecting rod 634 is located below the blocking plate 610. When the cylinder 411 is activated, the cylinder 411 drives the second trigger rod to move toward the toggle rod 633. After the second trigger rod abuts against the toggle rod 633, the toggle rod 633 drives the rotating sleeve 632 to rotate on the rotating rod 631, driving the connecting rod 634 to rotate, and the distance between the connecting rod 634 and the blocking plate 610 increases. The blocking plate 610 is driven to move downward toward the connecting rod 634 through the second transmission rope 635, thereby driving the blocking plate 610 to descend. In this embodiment, Figure 6 As shown, the toggle rod 633 gradually tilts downward from the cylinder 411 to the blocking plate 610, the left end of the toggle rod 633 is connected to the rotating sleeve 632, the connecting rod 634 is located above the toggle rod 633, the connecting rod 634 gradually tilts upward from the cylinder 411 to the blocking plate 610, the left end of the connecting rod 634 is connected to the rotating sleeve 632, and a fifth fixed pulley is also provided on the mounting frame 100 to steer the second transmission rope 635, the fifth fixed pulley is located below the blocking plate 610, and the second transmission rope 635 is wound around the fifth fixed pulley.

[0037] Based on the first to fourth embodiments, the working principle of an automatic feeding and emptying device of the present invention is as follows: As Figures 1 to 4 shown, the cylinder 411 is initially in an extended state. The turning table 430 is located at the bottom end of the linear guide rail 413. The turning table 430 is aligned with the discharge end of the feeding assembly 200. An empty box is located on the turning table 430. A full box is placed on the feeding assembly 200 and is blocked from sliding down by the blocking plate 610. The blocking frame 510 blocks the discharge port of the feeding assembly 200. When the control button is pressed, the cylinder 411 contracts. The cylinder 411 pulls the first transmission rope 412c, driving the turning table 430 to move upward. When the turning table 430 moves to the feeding port of the emptying assembly 300, the mounting plate 431 is blocked by the blocking rod 110 and rotates, causing the turning table 430 to tilt downward toward the feeding port of the emptying assembly 300. The empty box slides onto the emptying assembly 300 under the action of gravity; at the same time, the contraction of the cylinder 411 drives the second trigger rod to move. When the second trigger rod moves to abut against the toggle lever 633, it drives the toggle lever 633 to rotate around the rotating rod 631, and pulls the second transmission rope 635 through the connecting rod 634. The second transmission rope 635 causes the blocking plate 610 to move downward, allowing the full box to continue to move toward the blocking frame 510 under the action of gravity and abut against the blocking frame 510. The empty box moves on the emptying assembly 300 and touches the roller pneumatic mechanical valve, indicating that the empty box has completely entered the emptying assembly 300 and has been separated from the turning table 430. The roller pneumatic mechanical valve allows the cylinder to be ventilated, and the cylinder extends. The turning table 430 moves downward and resets under the action of gravity. The blocking plate 610 resets under the action of the elastic member 620 to block the subsequent full boxes. When the turning table 430 resets to the lowest end, the first trigger rod at the bottom end of the lifting frame 420 abuts against the lever, and the lever rotates, driving the blocking frame 510 to move upward, allowing enough space to be exposed at the discharge port of the feeding assembly 200. The full box moves onto the turning table 430 for the next cycle. The whole device has only one drive, that is, only the cylinder 411. The stable feeding of the full box and the stable emptying of the empty box are realized through the extension and contraction of the cylinder 411, shortening the production cycle on the basis of simple control.
